FIG 1.

H19 is significantly upregulated in pulmonary fibrotic tissues from IPF patients and is inversely correlated with the expression level of miR-140. (A) Representative images of normal and fibrotic tissues in lung from H&E staining assays. (B and C) qRT-PCR assays showed that pulmonary fibrotic tissues from IPF patients have higher H19 levels and lower miR-140 levels than normal lung tissues. (D) A negative correlation was observed between H19 and miR-140 expression in the lung tissues of IPF patients.
